“…In the literature, a number of studies report the microstructural formation of Al-Ni alloys under conditions of steadystate growth from the melt. [1][2][3][4] Mertinger et al [2] have examined the effect of natural convection on the macrosegregation of a eutectic Al-Ni alloy during vertical and horizontal Bridgman growth. JuarezHernandez and Jones [3] have analyzed the solidification microstructure selection of primary Al 3 Ni and eutectic in five different hypereutectic alloys of the aAl-Al 3 Ni system that were directionally solidified by the Bridgman technique.…”

“…The local solidification time is given by the following expression [15]: (2) where X is the position in casting from the metal/mold interface, αS is the solid thermal diffusivity and S 0 , L 0 can be expressed as a function of the metal/mold heat transfer coefficient (h i ), and are given by [15]: Figure 1 shows the casting assembly used in the experiments. It can be seen that heat is directionally extracted only through a water-cooled bottom made of carbon steel (SAE 1020), promoting vertical upward directional solidification.…”

“…The literature reports a number of studies analyzing the microstructural formation of Al-Ni alloys under conditions of steady-state growth from the melt [1][2][3][4]. However, there is a lack of consistent studies and experimental reports on the microstructural development of Al-Ni alloys during transient heat flow conditions, which are of prime importance since this class of heat flow encompasses the majority of industrial solidification processes.…”

“…Most of the studies existing in the literature focussing the interrelation of microstructure and mechanical properties are based on samples which were grown in steady-state solidification set-ups [2][3][4][5][6]. This means that the examination of Al-Ni alloys solidified under unsteady-state heat flow conditions deserves particular attention since this class of solidification can better represent industrial conditions.…”
